                                While the active ingredient, psyllium husk, is an indigestible fiber, many consumers are surprised to learn that some forms of Metamucil do contain calories. This caloric content primarily comes from added sugars and flavorings, depending on the specific product formulation. Understanding the nutritional differences between products is key to making an informed choice.
